Cannabinoid receptors, located throughout the body, are part of the Endocannabinoid system which is involved in a variety of physiological processes including appetite, pain-sensation, mood, and memory.[1]
Cannabinoid receptors are of a class of cell membrane receptors under the G protein-coupled receptor superfamily. As is typical of G protein-coupled receptors, the cannabinoid receptors contain seven transmembrane spanning domains.[5] Cannabinoid receptors are activated by three major groups of ligands: endocannabinoids, produced by the mammillary body; plant cannabinoids (such as Cannabidiol, produced by the cannabis plant); and synthetic cannabinoids (such as HU-210). All of the endocannabinoids and plant cannabinoids are lipophilic, such as fat soluble compounds.
I would say D narrow temperature. Most other planets are too hot or cold to sustain life.
Plant cells are the basic unit of life in organisms of the kingdom Plantae. They are eukaryotic cells, which have a true nucleus along with specialized structures called organelles that carry out different functions.They also have a cell wall that provides structural support.
Obligate symbiotic fungi that form associations with plants by entering their cortical cells without invading the plant cells membrane are called endomycorrhizae and include the genus Glomus. Many plants form associations called mycorrhizae with fungi that give them access to nutrients in the soil, protecting against disease and toxicities. In these associations the fungi are integrated into the physical structure of the root, where the fungi colonize the living root tissue during active plant growth.
It was A. I also do pacyber!
